Product Description:

The FVCA01.1-1K50-3P4-MNA-LP-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FVCA Frequency Converters series. It regulates the speed of three-phase induction motors by adjusting output frequency and voltage, making it suitable for pump, fan, and conveyor duty in automated plants. The unit accepts three-phase mains from 3 AC 380 to 480 V (-15% / +10%) and converts this input into controlled motor power for variable-speed operation. This allows the drive to match motor speed to process demand instead of running directly from fixed line frequency. Braking energy is managed by an integrated chopper with an external resistor, which keeps resistor heat outside the drive housing.

Its continuous output capability is 1.5 kW at 4.0 A with a nominal bus voltage of 400 V, and it presents 2.6 kVA of apparent power to the supply while drawing 5.1 A from the line. Space-vector pulse-width modulation operates at a default carrier frequency of 8.0 kHz. Field-oriented control accuracy is 0.05%, and sensor-vector control accuracy is 0.5% of maximum frequency. Frequency reference can be adjusted in fine increments, and control supports both encoderless and encoder-based modes. Eight digital inputs, an LCD panel, a built-in potentiometer, and ModBus networking provide local and remote command options. The front-panel controls allow basic setup and speed adjustment without external control hardware.

The mechanical layout uses frame size A, and the converter measures 275 mm in height, 125 mm in width, and 122 mm in depth. It mounts with M5 screws, weighs 2.7 kg, and carries an IP20 enclosure rating, so cabinet installation is expected. Its compact size helps it fit shallow control enclosures where panel space is limited. The converter does not include an output filter or an EMC filter. Speed resolution reaches 0.01 Hz, and closed-loop operation can cover a 1:1000 speed range, while open-loop control is limited to 1:100. SVPWM is used for modulation, and series line 01 with design revision 1 identifies the product version.
